Matlab2016a in Windows10 64 bites. The information of my Gpu
                        Name: 'Quadro K620'
                       Index: 1
           ComputeCapability: '5.0'
              SupportsDouble: 1

And I do this
vl_compilenn('enableGpu',true,'cudaRoot',...
'C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v7.5','cudaMethod','nvcc','enableCudnn',true,'cudnnRoot',...
'local/cudnn-rc4')
Then the error
Error using vl_compilenn>nvcc_compile (line 540)

Error vl_compilenn (line 485)
      nvcc_compile(opts, srcs{i}, objfile, flags.nvcc) ;
Please help me!I don't what the problem is.Please!

There is nothing obvious there. I would, though, recommend that you use a complete path for the last parameter. Also double check that you have write permission to the E:/MatconvNet etc directory described by that -o switch
